摘要:
The Invention comprises a body, an actuator pivotally connected to the body, and a retractable needle adapted to provide fluid communication between a patient and a fluid collection tube, typically a blood collection tube, attachable to the device. A significant feature of the subject device is a retraction cavity disposed inside the actuator that is manually positionable to receive a portion of the needle retraction assembly following removal of the blood collection tube. Retraction is initiated by depressing the forwardly extending end of the actuator relative to the body, thereby causing a retainer clip to release the needle holder, after which the needle holder and a part of the needle are propelled into the retraction cavity by expansion of a compressed spring. The needle is thereby withdrawn from the patient and into the housing, reducing the likelihood of accidental needle sticks and preventing reuse of the device.

A child safety and alert system and method that detect and monitor access and egress for assignable locations within a motor vehicle by identifying designated positions within the vehicle, by monitoring the driver door and other doors or closures in the vehicle, by activating a timer if the driver door is opened and closed, and by triggering an alarm if the designated doors or closures are not opened within a predefined time interval after the driver door is opened. The alarm can be deactivated from the driver seat or by a remote device. The system and method are similarly useful for alerting a driver to retrieve objects from storage locations within a vehicle.

This invention relates to medical devices useful for infusion therapy and, more particularly, to a syringe that can be selectively used with a retractable needle or with frontal attachment devices such as luer hubs, valves or other connectors in needleless systems.

摘要:
A passive intravenous (“IV”) catheter introducer having a spring-biased needle retraction system that is triggered when the needle is manually withdrawn through a catheter hub seal. The catheter hub seal constricts to block the rearward flow of bodily fluid and wipe potentially infectious fluids off the outer surface of the needle as the needle is manually withdrawn through the catheter sheath and seal following insertion of the catheter into a patient's vein. No additional steps are needed to activate the needle retraction mechanism beyond manual removal of the needle from the catheter hub seal.
摘要:
A non-reusable device for collecting bodily fluids such as vascular blood from a patient, the device being configured for example to receive a blood collection tube and having a retractable needle attached to a rearwardly biased needle holder that is constrained prior to needle retraction by a rotatably mounted lug ring and that is released during retraction by depressing a trigger pivotably connected to the body of the device to rotate the lug ring, whereby the needle holder is driven into a retraction cavity disposed inside the trigger and the front tip of the needle is retained inside the body of the device.
